Live-in nurse Maud (Morfydd Clark) arrives at the home of Amanda (Jennifer Ehle), a famous dancer now frail from illness and trapped in her grand, isolated house. At first, Amanda is intrigued by this religious young woman, who provides a distraction from her failing health. Maud, in turn, is bewitched by her new patient. But Maud is not all that she seems. She is tormented by a violent secret from her past and by ecstatic messages she believes are directly from God. She becomes convinced she has been sent to Amanda not simply as a nurse, but to serve a divine purpose. As her grip on reality slides out of control, Maud's care turns into a deadly mission to save Amanda's soul, by any means necessary.
